COLUMBIA, Mo. – The Mizzou Mobile Turfgrass Diagnostic Lab is a laboratory on wheels that can respond to turf problems on golf courses and sports fields quickly and effectively.

“The lab is outfitted with lab tools, microscopes and a workbench, which allows me to take a close look at the sample and identify the disease-causing agent,” said Lee Miller, turfgrass pathologist for University of Missouri Extension. “With the lab, turfgrass managers don’t have to wait while samples are shipped back and forth to a plant diagnostic lab.”

Many turf diseases can spin out of control if not treated in a timely fashion.

“We’re trying to keep a small problem from becoming a big problem by identifying and staving off disease,” Miller said.

Isaac Breuer, superintendent for the A. L. Gustin Golf Course in Columbia, says it’s important to respond quickly to turf problems during stressful periods in spring or summer.

“In the spring, we focus on dollar spot (and) brown patch as it gets warmer. In the summer we’re concerned with Pythium blight and Pythium root diseases,” Breuer said.

He notes that while the typical home lawn is mowed at 3 to 4 inches, putting greens are mowed to a tenth of an inch, which puts the turf under a great deal of stress.

There are number of diseases that will take advantage of that stress, Miller said. During the hot summer months of June, July and August, turfgrass is predisposed to diseases that can occur rapidly.

“It’s important for golf course superintendents and other sports turf managers to be able to resolve their problems in a timely manner and to implement management practices based on a very accurate diagnosis,” he said.

Miller said the response to the Mizzou Mobile Turfgrass Diagnostic Lab has been overwhelmingly positive. The lab has been able to provide fast diagnosis and treatment, helping to keep golf courses and sports fields in tip-top shape.
